(*) Time is in UTC (Universal Time Coordinated).
(*) Time is given in 1-minute increments for the sudden commencement type and in 0.1-hour increments for the gradual commencement type.
(*) "-1" is displayed for the range, when it is unknown due to missing measurements, etc.
(*) The range may not be determined for a storm which is followed by the next one before its ending (the ending time is indicated by "C").
